Divine Mother
Inspired by my reading of Yogananda, I have lately found it quite productive to talk some of the time with Divine Mother. I am the farthest thing from an expert on this topic, but based on some of my reading, I can say that the traditions of which Yogananda was a part view Divine Mother as the feminine aspect of God. She is seen as purely, unconditionally kind, loving, forgiving.
Now anyone engaged in the JWH protocol might say that your invisible friend should be all those things anyway. And that is absolutely true! The advantage of Divine Mother is simply that, for some, it may be easier to experience her immediately as all those things than might be the case with an invisible friend with a more masculine image. Divine Mother may be just a little easier to see as something akin to pure love. That in turn may make it easier to more quickly develop love for her. And it seems clear that the more emotional attachment you feel, the more love you feel, toward your invisible friend, the more potent that relationship will be in bringing about recovery.
Currently I'm spending more than half my time in the protocol talking with Divine Mother, while still spending the rest of the time talking with my original invisible friend.
Don't get too wrapped up in the decision concerning who you pick as your invisible friend. As JWH makes clear, it's best just to pick someone and get going. If need be, you can always switch to someone else. Do what works for you. Just don't overlook the possibility of Divine Mother!
